Synthesized as described for 1 using 1-tert-butyl-3,5-dimethylbenzene (5.76 mL; 30.81 mmol), chlorosulfonic acid (2.46 mL; 36.96 mmol) and anhydrous dichloromethane (200 mL). The crude residue was purified by automated silica gel column chromatography (Biotage®) eluting with ethyl acetate/hexanes (0 to 25% v/v gradient elution over 400 mL) to give the title compound as a white solid (1.60 g).
